The carbon tax aims to cut Australia's emissions by 5% from year 2000 levels by the year 2020, and bring emissions down 80% by 2050. Environment News. Latest green news Why the carbon tax should stay Jemma Green There is no shortage of people advocating to 'scrap the carbon tax', saying that it will reduce electricity prices and make Australia more competitive.
But it doesn’t stack up when you look at the numbers, says Jemma Green. Economy Is the world going to run out of food?

Advantages and Disadvantages of Global Warming. Updated April 04, 2010 In February 2007, the United Nations released a scientific report that concludes that global warming is happening and will continue to happen for centuries.
The report also stated with 90% certainty that the activity of humans has been the primary cause of increasing temperatures over the past few decades. With those conclusions and the conclusions of innumerable other scientists that global warming is here and will continue into the foreseeable future, I wanted to summarize the likely effects of global warming, into the advantages and disadvantages of global warming. First, we will look at the many disadvantages of global warming and then follow with the very small number of advantages of global warming. Disadvantages of Global Warming Ocean circulation disrupted, disrupting and having unknown effects on world climate. Advantages of Global Warming Arctic, Antarctic, Siberia, and other frozen regions of earth may experience more plant growth and milder climates.

Maps predict future floods for cities - ABC Melbourne - Australian Broadcasting Corporation. Updated December 15, 2010 11:57:00 Rising sea levels are likely to cause serious and regular flooding in Australian coastal cities by the end of the century, according to maps released by the Federal Government today.
The maps for low-lying areas in Melbourne, Sydney, Perth, Newcastle, the New South Wales' central coast and south-east Queensland show significant levels of inundation by the year 2100. The maps show three different scenarios, with the lowest rise of 50 centimetres representing a situation which is likely to be unavoidable. OzCoasts Climate change: Sea level rise maps. OzCoasts Climate change: Visualising sea-level rise - Melbourne region - Williamstown and Rosebud to Bass. Maps have been prepared for three sea-level rise scenarios of 0.5m, 0.8m and 1.1m,relevant for the 2100 period.
You may notice that some of the areas highlighted as low lying and vulnerable are the same ones that are already prone to flooding in big storms. However, it is important to remember that the maps show flooding that may occur annually, or in some areas more frequently, around the turn of the century. The big storms of 2100 are likely to flood an even larger area. The sea-level rise scenarios have been combined with a nominal highest astronomical tide (HAT) value for the region, and are based on IPCC projections and more recent science. The maps are based on a simple 'bucket fill' approach and should be considered as approximate only.
